The biggest floating solar farm in Europe is being constructed on a reservoir. More than 23,000 solar photovoltaic panels are being laid on the surface of the Queen Elizabeth II reservoir near Walton-on-Thames, Surrey. The farm, which will be the size of eight football pitches, is expected to generate 5.8 million kilowatt hours of electricity in a year. The energy will be used to part power a nearby water treatment works. Thames Water said construction of the solar farm, which is about eight miles (13 km) from Heathrow airport, will be completed by the end of March. The floating pontoon will be 57,500 sq m in size.

The power created by the farm will be the same as the annual consumption of about 1,800 homes, Thames Water said. The reservoir is run by the water company, while the farm is being funded and operated by solar energy company, Lightsource. Thames Water's energy manager, Angus Berry, said the farm would help the firm become a "more sustainable business".

Seems like a brilliant idea, I'm sure there must be a horrendous downside._________________Never mind, it's all anarchy isn't it?

Depends what they use to float the panels on C_E and what it introduces into the water. If they cover a significant area of the reservoir they could reduce the evaporation rate considerably as that reservoir is not very deep compared to its surface area and compared to some of the reservoirs in Wales, say, where the water depth is several times that of these above surface reservoirs._________________Action is the antidote to despair - Joan Baez
